VENT-CONTROLLER FOR CQOK-STOVES.

baking oven being 111' communication with a V vent in the hroiling compartment, which vent is provided with a controlling valve,

whereby said vent may be opened to permit fumes from the otherwise closed brolling I compartment to escape in a broilmg operation, the said controlling means being also manipulated to close the broiling compartment when it is desired to utilize the baking oven. By this novel arrangement it will be seen that when it is desired to broil in the compartment the valve or damper must be opened to give vent to the gases and fumes and when the broiling compartment is not used or when, for any reason, an intense fire is desired in the stove, as would be required in baking, the damp 1' must be closed so as to prevent checking the draft in the flue pipe.

Qther objects of my invention areto provide a simple one-piece cast grid-plate requiring no finishing, that is fitted about and secured to edges of a rear wall aperture of the bi'ciling compartment, the same being in communication with thesmokeflue; to pro ide the grid-plate with a valve-stem journal having a slot concentric therewith; to proide a lineally reciprcactive grid valve mem her that isslidably mounted and confined to one face of the rid-plate, said grid-plate member being also provided with a trans versely disposed crank-receiving slot; to provide a crank-carrying stem that extends through the front wall of the broiling compartment having :its rear end mounted in the grid-plate journal, the crank portion thereof being extended through the circular slot thereof and engageable with the vertically disposed valve slot; to provide a pointer head for the front end of the stem associated with an indicator plate, whereby Specification of Letters Patent.

the position of the valve is shown relative to the head, to thus indicate by the movement of the head whether the damper is positioned for broiling or baking purposes.

With the above and other minor objects in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying drawings and subsequentlyclaimed.

Inthe drawings Figure 1 represents a sec tional plan view ofa broiling compartment equipped with a vent controlling mechanism embodying the features of my invention, the section being indicated by line l1 of Fig. 2;'Fig.-2, a sectional elevation of the same, the Section being indicated by line 2.2 of Fig. 1; Fig. 3, a sectional face view ofthe valve mechanism, the section being indicated by line 33 of Fig. 2; Fig. i, an enlarged detailed sectional view of the valve mechanism, the section being indicated by line i& of Fig. 3; Fig. 5, an elevation of a portion of the front wall of the broiling compartment showing the controller head and related indicator plate, the elevation being indicated by line 5-5 of Fig. 2; Fig. 6, a detailed cross-section of the valve mechanism, the section being indicated by line 6-6 of Fig. 3, and Fig. 7, a dia grammatic view of a stove of ordinary type provided with an upper broiling compartment, which compartment is equipped with a valve-controlled vent that communicates with the smoke pipe of the stove.

Referring by characters to the drawings, 1 represents a broiling'compartment having a front wall 1 and rear wall 1, which rear wall is apertured to establish communication between the compartment and a fine 3 in the form of a rectangular smoke pipe.

The fine is centrally disposed with relation to the compartment, one side of which forms the broiling chamber that is divided from the opposite side by a wall 1'. Fitted to the rear wall aperture is a grid-plate 4 that is secured in position by stove-bolts which engage upper and lower flanges 4.

. The grid-plate is provided with vertically disposed vent apertures 5 and a segmental circular slot 6, which slot is concentric to a hollow boss 7 that is centrally apertured and cored to form a journal for one end of a valve-stem 8, which end is confined within the hollow boss by means of a split key flanges are also formed with inturned nibs- 13, whereby the valve-plate is confined, it being also confined by a split key, with which the end of the crank-pin 9 is provided. Attention is called to the fact that the nibs are positioned toward one end of the grid-plate, which is cored at the nib points, whereby the casting may be drawn and the said nibsformed without an extra operation, the manipulating crank being at the opposite end of the grid-plate, whereby the valve is confined atsaid end and may be reciprocated back and forth coincident to oscillation of the valve-stem.

As best shown in Figs. 1 and 2, the outerend of the valve-stem's is journaledin an aperture formed in the front wall 1 of'the broiling compartment and has secured to its extreme end a manipulating head 14: having a finger or pointer 1st projecting therefrom and when this pointer is inclined to the left, as shown, the compartment vent is open to the flue 3 and the pointer is directed toward the word Broil molded in an indicator plate 15. When the position of the head is shifted to the right the valve is closed and the pointer is directed toward the word Bake formed in the plate 15, it being understood that this movement of the head and valve is limited by engagement of the crank-pin with the ends of the circular slot that is formed inthe grid-plate. The circular movement described by said pin in transmitting movement to the valve member is compensated for bythe vertically disposed slot 10 in said valve-member. Hence it will be seen that when it is desired to broil the chef or cook shifts the head to a position where its pointer indicates- Broil and for baking to a position where the pointer is directed to the word Bake uponthe indicator plate. Thus the 'broiling compartment is cut ofi from the smoke flue, whereby the draft from the'i'lue space about the stove oven is not retarded. The compartment, as indicated, is provided with a Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents 7 burner 16 for direct gas heating and hence in a broiling operation the'fumes must necessarily be permitted to escape. .Attention is also called to the fact that the vent between. the compartment and flue is positioned at or near its top wall, whereby the fumes will readily be exhausted therefrom.

Referring to the diagram view, Fig. 7 A represents a baking oven of a stove of any desired type, which stove may be equipped with any fuel mechanism eitherfor' gas or coal. The fine pipe 3 is connected to the stove the ordinary manner and thebroil-q lng compartment is attached to the flue, as

shown, above the stove. The fiueis also provided with a check damper B, whereby'the' gases from the fuel may be deflected about the oven or discharged directly fromthe fire pot C thereof into'said smoke-flue. By. this construction it will be, observed, as pre-; viously stated, that the baking oven can be utilized in the ordinary manner and isnot affected by the broiling compartment in its operation due to the fact that the valve mechanism in said compartment cuts off communication between the same and the flue pipeB and when it is desired ,to-broil it is manifest thatthe valve mechanism in the compartment is opened, whereby the fumes from said compartment are permitted to escape. Thus a simple and effective combina: tion double compartment stove is produced wherein each compartment can be separately utilized without checking the drafts of the companion compartment. I

I claim: r

In a structure of the class described a grid plate provided with a vent aperture, 'a hollow boss formed on the plate, guide ribs on the plate, a valve plate'slidably held by said ribs, a squared actuating rod journaled in the boss, a stop carried by the rod in the hollow of the boss, an angular actuating member having one arm mounted on the rod and itsother arm extended through the plates, and a stop carried by the other arm I of the member and serving to hold the arm against movement on the rod and to hold the valve plate in place.

In testimony that I claim the foregoing I have hereunto set myhand at Milwaukee in the county of Milwaukee and State of WViscousin in the presence of two witnesses.
